看起来我的@Controller中的方法看起来不像@Secured.当使用基于sec:intercept-url的安全过滤时,这似乎工作正常.以下代码导致Spring Security向我提供此日志条目:

DEBUG:org.springframework.security.web.access.intercept.FilterSecurityInterceptor - 公共对象 - 未尝试身份验证

web.xml中

contextConfigLocation /WEB-INF/spring/root-context.xml

<!-- Creates the Spring Container shared by all Servlets and Filters -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- Processes application requests -->
<servlet>
    <servlet-name>appServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            /WEB-INF/spring/appServlet/servlet-context.xml
        </param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<!-- Filter security -->
<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

servlet-context.xml包含viewResolvers和所有编组的配置.此配置是注释驱动的.

根的context.xml

    <sec:global-method-security secured-annotations="enabled" />

<sec:http auto-config="true">
    <sec:http-basic/>
</sec:http>

<!-- Declare an authentication-manager to use a custom userDetailsService -->
<sec:authentication-manager>
    <sec:authentication-provider
        user-service-ref="userDetailsService">
        <sec:password-encoder ref="passwordEncoder" />
    </sec:authentication-provider>
</sec:authentication-manager> …

让我们从一些scalaz-stream文档中举例说明,但是有一个理论上的转折.

import scalaz.stream._
import scalaz.concurrent.Task

val converter: Task[Unit] =
  io.linesR("testdata/fahrenheit.txt")
    .filter(s => !s.trim.isEmpty && !s.startsWith("//"))
    .map(line => fahrenheitToCelsius(line.toDouble).toString)
    .intersperse("\n")
    .pipe(text.utf8Encode)
    .to(io.fileChunkW("testdata/celsius.txt"))
    .run

// at the end of the universe...
val u: Unit = converter.run

在这种情况下,文件可能包含一些非双字符串,并且fahrenheitToCelsius会抛出一些NumberFormatException.让我们说在这种情况下,我们希望记录此错误并忽略它以进行进一步的流处理.这样做的惯用方法是什么？我见过一些例子,但他们通常collectFrom是流.
